The client-side counterpart of Crit-Fumble's hosted Factorio servers.
When a hosted server has its service link enabled, this mod exposes a
small remote interface ("cfg") that the platform reads over RCON:
a structured status snapshot for the server dashboard, and in-game
announcements from the server owner (shown as [CFG] chat lines).

• Control-stage only. No prototypes, no gameplay changes; adding
  or removing it never alters a map.
• Fully sandboxed. Factorio mods cannot access the network or your
  files. This mod never phones home — the server reads it over RCON.
• Inert elsewhere. On a save without a Crit-Fumble server behind
  it, it does nothing at all.
• Never asks for tokens, credentials, or anything outside the game.
